Lanthanide ion-induced hydrolyses of methyl esters, ethyl esters, and amides of α-amino acids were systematically studied. In the hydrolysis of the alklyl esters, all the lanthanide ions are effective and the catalytic activities decrease in the order Ce(III), Nd(III) > Sm(III) > Eu(III) > Gd(III), Ce(IV) > Pr(III) > Dy(III), Tb(III), Er(III), Ho(III) Tm(III) > La(III), Lu(III), Yb(III). For the hydrolysis of the amides, however, the Ce(IV) ion is overwhelmingly more active than other lanthanide(III) and non-lanthanide ions. The results are interpreted in terms of the difference in the rate-limiting step for these two reactions.
